Hello John:

They must face the same direction as the LEDs. I have LEDs all over my layout, signals, power indicators, etc. and have never added more than the 1K resistor to them. All run from DCC track power.

Thanks, Don.  Does it matter which direction the diode faces?

Don’t forget to include a diode to protect the LED strip from reverse voltage. (if it doesn’t already include a rectifier.) Use a single resistor to limit current and brightness.

Hi! I am investigating the multiple possible methods of lighting coaches/carriages on my HO NCE controlled layout.  I have tried Flicker Free, which works fine.  I have also built small circuits using miniature rectifiers feeding LED strips.  In order to light my entire collection using any of these methods, a significant investment in time and electronic components would be required.  I have tried a small experiment using direct DCC track power to light a short strip of LED lights and found it worked fine, especially with the addition of a 1K resistor in series in the circuit.  Is this approach too simplistic or am I missing something?  Any comments appreciated!  Thanks in advance,

John Cahill
